R-M222 Haplogroup Project (formerly the R1b1c7 Project) - Goals

Some genetic diversity exists within the haplogroup. Subclusters have not been distinguished based on the STR values alone, but it is known that some families have distinctive values at particular markers. Among the goals of the project will be

(1) To draw geographical distinctions and establish further clan and family subclusters within the R-M222 haplogroup.

(2) To establish the distribution of the pattern before the great migrations of the last 350 years.

(3) To establish the age of the haplogroup, which has been variously estimated from 2,000 years to nearly 8,000 years.
